Application filed February 5, 1910. Serial No. maid.

To all whom it may concern: I Be it known that I, HENRY OIJHS'TE'D, Jr., a. citizen of the United States, residing in the borough of Brooklyn, county of Kings,

and State of New York, have invented new and useful Improvements in Roofing, of which the following is a sfi'ecification.

My invention relates to improvements in roofing, its object being to provide an improved constructiomof thesaime, whereby a surfacin of concrete can be applied to a,v

waterproof covering oftarred felt paper or other fabric irrespective of the pitch or incline of the roof, and consists of the features of constructionhereinafter shown, described and claimed.

In the accompanying drawings forming cured upon the roof-boards in overlapping layers in the ordinary manner. Upon each layer of the felt 3 is arranged a series of metal strips 4:, the inner or upper 'ends of which are secured to the rcof-boards 2, prefcrably beyond the edge of the felt 3 so as to avoid puncturing the felt, the other being perforated. and upturned to form the stud 5, which stands just below the exposed edge of the nextlayer of superposed felt.

(3 is the coating of tar or asphalt which is applied to the complete feltcovering.

Threaded through the openings of the studs 5, is a rod 7 which serves to secure in place just above the tar covered felt, a in'etal reinforcing element 8 of any suitable character. The roof is finished by applying a surfacing of concrete 9 embedding the underlying metal parts. The studs 5 serve to hold the reinforcin element from dis placement laterally, wiile the rods 7 prevent it from buckling or rising toohigh above the felt or out of engagement with pitch, and\is held firml means of the bars 4 w ich are secured the studs, whereby secure anchorage forthe concrete is attained. By means of this construction the reinforcin layer of concrete can be applied to a roo of practically any 1n ,position by firmly to the roof, but without injury to the layers of felt which would make them less impervious to moisture. -The surface of the concrete may be iveir' any desired finish, either smooth or indented into any desired markings or configurations to imitate tiles or other roofing materials.

I claim,

1 A. compositeroofing, comprising overlapping layers of water-proof fabric, sinuous anchoring devices projecting between said over-lapping layers Without penetrating the same, a reinforcing elementfor'con' crete positioned above said over-lapping layers, retamlng means for the unitary connection of distant portions of said reinforcmg element, means for positively securing said retaining means to vsaid anchoring. meafis, and a cementitious layer embedding said reinforcing element and intimately contacting with the uppermost layers of fabric.

' 2. A composite roofing, comprising overcrete positioned above said over -lapping layers, retaining means for the unitary connection ofdistant portions of said reinforcing element, means fol-positively maintaining said retaining means out of contact with the uppermostlayers of' felt and for securing said retaining means to said anchoring devices, and a cement-itious layer embedding said reinforcing element and in' timately contacting with the'- f uppermost layers ,of fabric.

A composite roofing, comprisili' overla ping layers of fabric, sinuous anc oring d vices extendingv completely through said layers. without the rectilineal penetration there0f,'&nc1 projecting upwardly to apoint" In' Witness whereof I have hereunco SQET substantially distant from the uppermost my hand at the city of New York this layers of said fabric, and a cementitious day of January 1910.

layer of material completely enveloping the HENRY ULY-ZESTEB J21 uppermost ends-0f said anchoring devices, Witnesses:

and intimately contacting with the upper- D. W, KINCAID, moat layers of fabric. L. P. LEWIS.
